Specification of Letters Patent;

1Pateirit'edill tine 13 19422 Application filed October 27, 1920. Serial No. 420,021.

To all whom it may concern Be it known that we, FREDERICK CRATE and drums BARNETT, citizens of. the United States, residing in the city of Martinez, in the county of Contra Costa. and State of California, have invented a new. and useful Improvement in a Mop lVringer, of which the following is a specification.

Our invention relates to improvements in mop wringers wherein a slidably. and rotatably mounted mophead is operated to twist the strands of a. mop to wring fluids therefrom.

The primary-object of our invention is to provide'an improved mop wringer.

Another object is to provide an improved mop head adapted to facilitate the wringing of fluid from a mop attached thereto.

A further object is to provide a device of simple and durable construction adapted to be operated to twist the strands of a mop attached thereto for wringing fluid from said mop.

lVe accomplish these and other objects by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are use to designate similar parts throughout said specification and drawings and in which,

Fig. 1. is a. broken front elevation of a mop attached to our improved mop-head,

Fig. 2. is a broken side elevation of Fig. 1.

Fig. 3. is a view similar to Fig. 2. with the mophea-d moved to twist the strands of the mop.

Fig. 4, is an enlarged detail view taken along the line .1-4 of Fig. 2.

Referring to the drawings, the numeral 1 is used to designate in general a mop attached in any suitable manner to a mop head 2 provided with a shank 3 arranged to be engaged and guided by a bearing 4- pivotally mounted between lugs 6 formed upon the lower part of a sleeve 7 secured to a suitable handle 8. The mop 1 is made preferably from a plurality of twisted strands arranged in loops, but any suitable fibrous material adapted to be attached to the head 2 as a continuous web may be substituted. The webs or twisted strands from which the mop 1 is formed are looped over a stirrup 8 formed integrally with or secured to the sleeve 7, said stirrup 8 extending downwardly therefrom a distance substantially equal to the length of the mop 1.

An operating lever 9 havingbifurcations 11 formed at one, end thereof. is plvotally. mounted upon the sleeve 7. by meansof. a

bearing pin 12 rotatably mounted in a lug:

1 1 formed at the upper end of the sleeve 7.

A grip 16 is provided at the outer end of" the operating lever 9 to facilitate gripping by the hand of an operator. The bifurcations 11 are arrangedto extend ateither side of the sleeve 7 to engage the upper end ofthe shank 3in a manner hereinafter described.

The shank 3 is'made as a screw of. rela: tively. steep pitch. In our'present practice the shank 3is formed by. twistingasquare bar a. sufficient number of times to obtain.

a spiral of the desired pitch. The bearing 4: is apertured to conform to the shape and pitch of the twisted shank 8. The upper end of the shank 3 is provided with a collar 16 rotatably mounted thereon between flanges 17, said collar 16 being provided with hearing pins 18 extending laterally from opposite sides thereof and arranged to be engaged by apertures 19 provided in the outer ends of the bifurcations 11, whereby said bifurcations are rotatably and pivotally secured to the shank 3.

The lower portion of the stirrup 8 is provided with a. lateral cross bar 21 upwardly offset at 22 to assist in retaining the mop 1 in operative relation to the end of the stirrup 8.

In operation the mop-head 2 is depressed to the normal position disclosed in Fig. l of the drawings, the mop 1 passing through the stirrup 8 and over the offset crossbar 21, and utilized in the. usual manner. .lVhen it is desired to wring water or other fluid from the mop 1, the operating handle 9, which is arranged to normally lie adjacent the mop handle 8, is moved outwardly and downwardly about the bearing 12, thereby causing a corresponding upward movement of the bifurcated ends 11. As the shank 3 is advanced upwardly through the guide bear ing 1, a rotative movementis caused by engagement of the spirally disposed sides of the shank with the correspondingly apertured guide 4. The rotatable collar 16 and the pivotally mounting of the guide 4: upon the lugs 6 permit the simultaneous rotation and longitudinal advancement of the shank 3 and the head 2. As the mop head 2 is advanced the mop 1 is moved upwardly over the stirrup 8, the lower portion of the mop being engaged by the offset crossbar 21 and causing the mop to be twisted by the rota: tion of the mop head 2. As the mop head is rotated continuously during the upward movement of the shank 8 the mop becomes twisted to a corresponding degree and the fluid thereby forced out. It is obvious that the greater the number of twists caused in the mop by advancement of the shank 3, the more complete will be the expulsion of fluid therefrom.

'A spring 24 may be provided about the shank 3 between the mop head 2 and the bearing 4c to assist in returning the mop to its normal position after having been displaced lor wringing.

*laving thus described our invention what we claim as new and desire to secure by Letters Patent is:

A mop wringer comprising a handle; a sleeve fixedly secured upon one end or the handle; a stirrup formed integrally with said sleeve and extending in longitudinal alignment with the handle to receive one end of a mop; a mop head arranged to engage the other end of said mop; a guide pivotally mounted upon the sleeve and having a spiral bore therein; a spiral shank secured upon the mop head and passing upwardly through the spiral bore of the guide, said guide operating to impart a rotative movement to the shank and mop head when said shank is moved longitudinally there-- through; an operating lever pivotally mounted upon one side of the handle; bifurcations formed upon the lever and extending past the handle upon either side thereof; means for rotatably connecting the shank to said bifurcations whereby rotative movement of the shank and head will operate to move the lower end of the mop into engagement with the stirrup and twist said mop between the head and the stirrup when said operating lever is actuated to move the shank longitudinally tl'lrough the guide; and

means for returning said mop head to a norma-l position after each operation.

In witness whereoi' we hereunto set our signatures. I

FREDERICK CRAIB. JAMES BARNETT.
